Packaging Overview
Prerequisites
To build packages, install the devscripts package: sudo apt install devscripts, which contains a lot of useful helpers for building Debian packages.
Having gbp available is also a good idea: sudo apt install git-buildpackage
Note that installing git-buildpackage (gbp) will pull in pbuilder. You can prevent this by using --no-install-recommends when you install, e.g.;
apt install --no-install-recommends git-buildpackage
This is not necessary but can be helpful if you don't want to install and configure pbuilder.
Building packages
All packages should be testbuilt in a pristine PureOS landing chroot before being uploaded to PureOS. The preferred method to do that is by using either pbuilder or debspawn.
Debspawn quickstart
Debspawn is using a systemd-nspawn container to build the package in. It is also the build environment used on the PureOS autobuild servers, so if you want to replicate a build as close as possible to what runs on our build servers, use debspawn.
To install debspawn, run sudo apt install debspawn first.
Then create a new build environment for landing: debspawn create landing.
For packages not managed in Git, debspawn can be invoked via
debspawn build landing --sign
For Git-managed packages, gbp can be instructed to build with Debspawn via gbp buildpackage --git-builder='debspawn b landing --sign'
Don't forget to set your own email address for the Git repository, via git config user.email your.name@puri.sm.
Pbuilder quickstart
There is documentation on setting up a pbuilder environment using PureOS.
For packages not managed in Git, pbuilder can be invoked via
DIST=landing pdebuild --auto-debsign
For Git-managed packages, gbp provides options to build with pbuilder directly. Alternatively, pdebuild can be passed in like gbp buildpackage --git-builder='DIST=landing pdebuild --auto-debsign'
Don't forget to set your own email address for the Git repository, via git config user.email your.name@puri.sm.
Version numbers
Packages which are available on Debian and are changed in PureOS have a pureosX version tag attached to the Debian revision, with X being the PureOS revision number. So, if the package's upstream version is 2.1, it's Debian revision is 2 (creating the Debian version string 2.1-2) and you make a change for PureOS, the resulting package version must be 2.1-2pureos1. The PureOS revsion is incremented with every change, so the next version would be 2.1-2pureos2.
If the package isn't in Debian, the Debian revision number is assumed to be zero and all other rules from above still apply. So, and upstream package with version 3.4 which is new in PureOS will get the initial version 3.4-0pureos1.
If you do not do any source changes but just rebuild a package, bX is appended to the revision. So, a package of version 1.0-3 gets the new version 1.0-3b1 if it is rebuilt. The rebuild version is incremented on every subsequent rebuild.
If the archive rejects an upload because a +bX version number exists, then this is because of a binary package sync from Debian where the package was binNMUd before. In this particular case, please upload the package again, but append a + before the PureOS version, so 1.0-1pureos1 becomes 1.0-1+pureos1.
Paying attention to the version numbers is important, because the PureOS archive tools will use the version number to make decisions about the package's state, which includes overriding it with a version from Debian or even removing it.
Using the right version number will make the archive do the right thing.
You might be able to use DEBEMAIL=first.last@puri.sm dch --distribution=landing --force-distribution --no-auto-nmu --local=pureos as a starting point.
Validating packages
Use lintian --profile=pureos -IE --pedantic <changes-file> to check a package for compliance with the Debian policy. Ensure it is warning and error-free.
If your Lintian is old and does not support the pureos profile, all warnings related to NMUs and invalid suites can be ignored, as those are different or don't exist in PureOS. (See https://bugs.debian.org/884408)
Maintainer address
If you change the maintainer address in a Debian package you modify, please use PureOS Maintainers <pureos-project@puri.sm>. You don't actually need to change the maintainer address (it is a bit nicer though). In any case, you don't need to add yourself as uploader, since all packages in PureOS are team maintained - the Lintian error for that is something we might need to change.
Closing bugs
To close bugs in the PureOS tracker with an upload, use either the PB: #<nnn> or PureOS: #<nnn> syntax in debian/changelog, with <nnn> being replaced with the number of the respective task in Maniphest on tracker.p.n (with the T prefix stripped).
At the moment, the service that automatically closes reports is not active, due to maintenance (the previous implementation had a few bugs and was very slow), so for now you will need to close bugs manually. However, for some packages the bug information is still used to e.g. determine package migration speed.

Event Timeline
Feel free to delete my draft which arouse out of confusion around the Uploaders: field ;)
I would delete it myself, but have no clue how :O
@evangelos.tzaras no idea how one drops drafts but i think i restored the original version.
the main development branch should be called debian/latest
I believe that should be pureos/latest instead.
So would that be pureos/latest (instead of pureos/byzantium) and pureos/amber or pureos/amber-phone then?
Confusing!
Using pureos/byzantium or pureos/amber with or without -phone is somewhat easier for me since it clarifies which branch is destined for which target suite. In my mind, pureos/latest points to the branch that you work from to create pureos/*.
- @guido Am I right in this thinking with pureos/latest?
- @evangelos.tzaras How can we make this less confusing?
I was mostly confused whether this would imply that we would have both pureos/latest and pureos/byzantium.
Might also have been a case of -ENOCOFFEE, so feel free to disregard the confusion ;)
@evangelos.tzaras you only have *both* `pueros/latest and pureos/byzantium once byzatium is no longer the current development version. See https://dep-team.pages.debian.net/deps/dep14/ . The upside of pureos/latest is that you'd not be constantly busy with switching the repos default branch and name. It's basically the same as we do within DebianOnMobile with debian/master.
